12 LED lamp power driver is good But not all bright can fix
This kind of situation should be how to I have several are the problem They can't spell some of my good to come out
This is all 12 lights series, if really bad one, all all is not bright, but the short it is ok to pick up the bad. You can live under test lamp red black line on the board, the normal light bead on the voltage should be within 36 to 40 v. If the drive is normal, and light bead is broken is not bright, voltage should be in more than 50 v, even more than 200 volts.
This thing I'll fix it Will the multimeter test? Drive if I said above is normal lamp bead is broken, the multimeter diode test, bright is good, not bright either yourself in lamp bead, or directly short answer
